AMD Radeon RX 7800M vs NVIDIA GeForce RTX 3070 Ti Comparison

The benchmark data presents a clear split between these two GPUs. The NVIDIA GeForce RTX 3070 Ti is the decisive winner in raw performance across the vast majority of tests, taking 9 out of 10 head-to-head matchups, while the AMD Radeon RX 7800M secures a single but notable victory in one compute workload. However, the RTX 3070 Ti is a desktop card with a 290 W TDP, whereas the RX 7800M is a mobile IGP solution with a 180 W TDP, which fundamentally changes how these results should be interpreted.

Where Each One Wins

The NVIDIA GeForce RTX 3070 Ti dominates in almost every measurable category. Its largest victories come in legacy DirectX tests, where it leads by 56.6% in DirectX 10 and 50% in DirectX 9. It also shows a substantial 32.6% lead in the Passmark G3D test and a 24.2% advantage in Passmark GPU Compute. In modern 3D workloads, the RTX 3070 Ti wins the 3DMark Steel Nomad DX12 test by 16.2% and the Geekbench Vulkan test by 10.2%. The data clearly shows this NVIDIA card is the superior performer for gaming and general 3D graphics.

The AMD Radeon RX 7800M’s single win comes in the Geekbench OpenCL test, where it scores 120778 against the RTX 3070 Ti’s 119718, a margin of just 0.9%. This is a narrow victory in a compute-oriented benchmark, suggesting a slight advantage in certain general-purpose compute tasks that leverage OpenCL. Outside of that specific test, the RX 7800M trails in every other category, including a 9.1% deficit in DirectX 11 and a 2.2% deficit in DirectX 12. The AMD card’s performance profile is therefore best described as competitive in compute but clearly behind in rasterization and legacy API workloads.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process technologies. The NVIDIA GeForce RTX 3070 Ti uses the GA104 chip based on the Ampere architecture, manufactured on Samsung’s 8 nm process. It packs 17,400 million transistors on a 392 mm² die, resulting in a transistor density of 44.4M per mm². In contrast, the AMD Radeon RX 7800M uses the Navi 32 chip with RDNA 3.0 architecture, built on TSMC’s 5 nm process. This newer node allows AMD to fit 28,100 million transistors on a smaller 346 mm² die, achieving a much higher density of 81.2M per mm².

Memory configurations differ significantly as well. The RTX 3070 Ti features 8 GB of GDDR6X memory on a 256-bit bus, delivering 608.3 GB/s of bandwidth. The RX 7800M offers more capacity with 12 GB of GDDR6 memory but on a narrower 192-bit bus, resulting in lower bandwidth of 432.0 GB/s. The NVIDIA card compensates for less capacity with faster memory technology and higher bandwidth. Clock speeds also tell a story: the RTX 3070 Ti has a higher base clock at 1575 MHz but a lower boost clock at 1770 MHz, while the RX 7800M starts lower at 1295 MHz but boosts much higher to 2335 MHz, with a game clock of 2145 MHz.

The compute configurations are radically different. The RTX 3070 Ti has 6144 shading units, 192 TMUs, and 96 ROPs, along with 48 RT cores and 192 tensor cores. The RX 7800M has fewer shading units at 3840 but more TMUs at 240, with the same 96 ROPs. It has 60 RT cores and no tensor cores, reflecting AMD’s different approach to accelerating AI workloads. Despite having fewer shading units, the RX 7800M achieves higher theoretical FP32 performance at 35.87 TFLOPS versus 21.75 TFLOPS for the NVIDIA card, thanks to its higher clock speeds.

The Verdict

For users prioritizing pure gaming and 3D rendering performance, the NVIDIA GeForce RTX 3070 Ti is the clear choice based on the data. It wins 9 of 10 benchmarks, with particularly strong showings in DirectX 9, DirectX 10, and Passmark G3D tests where it leads by 50% or more. Its 16.2% advantage in 3DMark Steel Nomad DX12 is a strong indicator of modern gaming capability. The RTX 3070 Ti also holds a 10.2% edge in Geekbench Vulkan, making it the better option for Vulkan-based titles and applications.

The AMD Radeon RX 7800M, however, is not without merit. Its 0.9% win in Geekbench OpenCL suggests it may be preferable for certain compute-heavy tasks that utilize OpenCL. Its higher FP32 throughput of 35.87 TFLOPS compared to 21.75 TFLOPS indicates theoretical compute superiority, even if the benchmark results do not always reflect this. The RX 7800M also offers more memory at 12 GB versus 8 GB, which could be beneficial for applications with high VRAM demands. Crucially, the RX 7800M is a mobile IGP with a 180 W TDP, making it suitable for portable devices, while the RTX 3070 Ti is a dual-slot desktop card with a 290 W TDP requiring a 600 W power supply.

The verdict depends entirely on the use case. For a desktop gaming rig where power and space are not constraints, the RTX 3070 Ti is the superior performer. For a portable device where power efficiency and lower heat output are critical, the RX 7800M is the only viable option despite its lower benchmark scores. The data shows the RTX 3070 Ti is the faster card, but the RX 7800M is the more efficient and portable solution.
